I am not sure if this is the right place for asking Work related questions. This is more of an e-mail group of people trying to work on getting there CCIE.

Sorry for not giving the feedback for the issue we had a couple of weeks ago. The problem was BGP conflict. Our isp was announcing the IP range with his AS number and another ISP in US was still advertising the same IP range with another AS number to the Internet. So, when troubleshooting through reverse traceroutes, the traffic was sent to US when the AS path was short and to our country when our AS path was shorter than he one originated from the US. We finally arranged that with the provider in US and everything was fine. But actually, we sometimes have access to some web sites but can't open or download something at sometimes and everything get's back to normal without any configuration change. I can't understand what is going wrong.

Hello all ! Am Working with an ISP and noticed that some customer can not download their mails some times and download informations from certains web sites. When thathappens, pings are OK. We can still access the web sites but cannot download something. I don't know how to troubleshoot some applications and find out what isgoing wrong. Thanks !
